夜色中的地球（2020）

夜
The night.
一个暗影重重的世界 那里藏着地球上超过一半的动物
A shadowy world that hides more than half the animals on our planet.
在过去的镜头中 我们只能匆匆一瞥动物的生活
Until now, cameras only offered a glimpse into their lives.
但凭借新一代科技
But with next-generation technology,
我们眼中的夜晚和白天一样清晰
we can see the night as clear as day.
有了比人类眼睛敏感100倍的摄像机
With cameras a hundred times more sensitive than the human eye. . .
我们终于能够捕捉到夜晚的美
we can now capture the beauty of night. . .
以全真色彩
in color.
怪谲的自然风光
Alien landscapes.
在黑夜里活跃的奇特生物
Strange creatures brought to life by the darkness.
前所未见的行为
Unseen behaviors.
现在我们能追踪动物的生活
Now we can follow the lives of animals
前往地球最后的荒野
in Earth's last true wilderness.
夜
The night.
在肯尼亚的马赛马拉 又一天结束了
Another day draws to a close across Kenya's Maasai Mara.
非洲狮的最后一处栖息之所
A last refuge for Africa's lions.
这里的草原栖居着 这个三代同堂的狮子小家庭
The grasslands here are home to three generations of a small family.
六只处于青春期的狮子
Six adolescents.
一只雄狮
A pride male.
和一位尽心竭力的母亲
And one devoted mother.
母狮
The lioness.
它有三只新诞生的幼崽
She has three new cubs.
幼崽只有十周大
At ten weeks old,
还无法保护自己
her youngsters are too small to defend themselves. . .
但已经开始惹麻烦了
but big enough to get into trouble.
接下来的几周对于这位母亲而言 会是前所未有的考验
The coming weeks will test this mother more than ever.
三只幼崽中只有一只左右能存活过一周岁
Only around one in three cubs make it through their first year.
白天 母狮子必须休息
By day, the lioness must rest.
因为一旦太阳落山
Because as the sun sets. . .
它的工作就开始了
her work begins.
狮子主要在夜间行动
Lions are largely nocturnal. . .
80%的活动是在天黑后进行的
living out 80% of their lives after dark.
过去我们一直无法全面地了解
We've never been able to tell the full story
母狮和它的家庭在夜晚如何生活
of a lioness and her family at night.
但史上第一次
But for the first time,
低光度摄像机能够展现 它们在月光下的世界
low-light cameras can see their moonlit world. . .
以全真色彩
in color.
这一捕捉夜晚景象的全新方式令人惊艳
This astonishing new way of seeing the night
为理解狮群生活提供全新视角
offers a whole new understanding of lion family life.
夜幕刚落下时
At the start of the night,
家庭中的一位重要成员不见了
one important member of the family is absent.
雄狮要四处巡逻
The pride male is out on patrol.
它的职责是守卫40平方公里的领地
His job is to protect his 40-square-kilometer territory
驱赶敌对的狮子
from rival lions.
它的吼声是一种警告
His roar is a warning call
在夜晚天气凉爽时 这个声音能够传到很远的地方
that travels further at night when the air is cool.
它以超过100分贝的声音吼叫
Bellowing at over a hundred decibels. . .
8公里外都能听见它的声音
he can be heard eight kilometers away.
这份工作显然很消磨精力
It's clearly exhausting work.
但它不遗余力
But he gives it everything he's got. . .
只为了让家人在黑暗中不受侵害
to keep his family safe in the darkness.
在雄狮的保护下
Protected by the male,
母狮在夜晚的第一个职责是喂幼崽
the lioness's first job of the night is to feed her cubs.
十周大的幼崽
At ten weeks old,
完全依赖母乳为生
cubs are entirely dependent on milk from their mother
每天晚上最多能喝1升
and can each drink up to a liter a night.
喂饱幼崽后
Once she's fed them. . .
母狮让它们和哥哥、姐姐们在月光下玩耍
she lets them play with their older brothers and sisters in the moonlight.
狮子在夜晚不仅更活跃
Lions aren't just more active at night.
社交行为也更多
They're also more social.
虽然幼崽还小 但它们已经开始学习打斗
The cubs might be small, but they're already learning to play fight.
不过 如果玩得太激烈
But if things get too boisterous. . .
母狮就要出场了
the lioness steps in.
玩耍时间…
Playtime. . .
到此结束
is over.
作为最有经验的雌性 母狮必须为整个狮群捕食
As the most experienced female, the lioness must feed the whole pride.
但身后跟着幼崽 它无法捕猎
But she can't hunt with her cubs in tow.
从人类的眼睛看来
To the human eye. . .
这几乎是漆黑一片
it's almost pitch black.
但透过我们的镜头可以看到
But our cameras show. . .
为了给全家捕猎
that to hunt for her family,
它不得不抛下幼崽
her only option is to abandon her cubs.
小家伙们失去了保护
With her little ones unguarded. . .
母狮知道自己必须快速行动
the lioness knows she must work fast.
狮子以群体捕猎著称
Lions are known for hunting as a pride.
但今晚是个例外
But tonight. . .
母狮不打算倚赖团队工作
the lioness doesn't rely on teamwork.
凭借比我们敏感六倍的夜间视力
With night vision six times more sensitive than ours,
它选中一群角马
she picks out a herd of wildebeest.
顺风靠近
Approaching from downwind,
它必须距离猎物30米内
she must get within 30 meters of her prey.
它凭一己之力完成猎杀
She makes the kill all on her own.
一头成年角马能喂饱一整个家庭
An adult wildebeest will provide food for her whole family
作为两天的食物
for up to two nights.
但母狮不能休息太久
But the lioness can't rest for long.
它必须回到幼崽身边
She must get back to her cubs.
夜里在草原上捕猎的不只是狮子
Lions aren't the only animals to hunt these grasslands by moonlight.
斑雕鸮
An African eagle owl.
凭借天生适应黑暗的眼睛
With eyes adapted for the darkness. . .
和能够降低噪音的锯齿状翅膀
and fringed wings that reduce noise. . .
它无声地俯冲 突袭啮齿动物和爬行动物
he swoops silently down on rodents and reptiles.
但在满月之夜 它会被日常的猎物看见
But under a full moon his usual prey will see him coming.
于是它将目标改为藏在草中的小型猎物
So instead he targets smaller victims hiding in the grass.
为了捕捉猎物 斑雕鸮必须飞下枝头
To catch them, the eagle owl must get off his perch
徒步追捕
and chase them down on foot.
相较于平日的食物 狼蛛是个美味的调剂
A wolf spider makes a tasty supplement to his normal diet.
但如要取得与老鼠等量的卡路里
But to get the same calories he'd find in a mouse. . .
它必须捉到30只蜘蛛
he'll have to catch up to 30 spiders.
斑雕鸮在夜晚捕食的动物超过60个种类
With more than 60 different species on his nightly menu,
可以说它并不挑食
the eagle owl isn't exactly a fussy eater.
回到狮群
Back with the pride. . .
狮子家庭仍在美餐
the family is still feasting.
但母狮听见了危险的声音
But the lioness can hear danger.
鬣狗
Hyenas.
这些夜行食腐动物 会偷走狮子所猎杀的20%食物
These nocturnal scavengers steal around 20% of lion kills.
雄狮听见了动静
The pride male has heard the commotion.
一只成年公狮子就足以驱赶一整群盗猎者
A single adult male is powerful enough to drive off an entire mob.
现在 它想要自己的那份食物
Now he wants his share of the kill.
就连母狮
And not even the lioness. . .
都不能挡它的道
can stand in his way.
母狮不得不丢下自己捕猎的食物
Bullied off her own kill. . .
再加上虎视眈眈的鬣狗
and with hyenas at large,
它必须找到三只幼崽
the lioness must now find her three cubs.
低频的闷声呼叫是母狮召唤幼狮的方式
A low-pitched grunting call is how lion mothers summon their youngsters.
一只幼崽安全了
One of the cubs is safe.
但另外两只仍不见踪影
But the other two are missing.
幼崽在夜间走失几个小时并不罕见
It's not uncommon for cubs to go astray for a few hours at night.
但若在附近 它们通常会回应母亲的召唤
But they usually respond to their mother's contact calls if they're close by.
幼崽的低声呼叫是不安的表现
Her young cub's meows are a sign of distress.
它在暗夜里搜寻幼崽的踪迹
In the darkness, she scans the night for any trace of her cubs.
在找到它们前 它不会放弃
She will not give up until she finds them.
三天后
Three days later. . .
虽然在自己的领地各处不断呼叫
and despite calling day and night across her territory. . .
母狮仍然没找到走失的幼崽
the lioness still hasn't found her missing cubs.
没有母乳的哺育 幼崽很难存活四天以上
Without milk, cubs will struggle to survive beyond four days.
此刻的情况不太妙
The odds are now stacked against them.
第四个夜晚降临了
A fourth night draws in.
它的搜寻仍在继续
Her search continues. . .
身后跟着小狮子
with her little one in tow.
它的不言放弃是正确的
